Answer:

Area: 9 cm^{2}

Step-by-step explanation:

Since all sides of a square have equal lengths, the area of the square is a^{2} (a = length of a side).

Since the length of the side of the square is given (is 3cm), the area of the square is (3cm)^{2} =  9cm^{2}

We can Notice From the Figure that the Sides of the Triangle are Equal.

If a Triangle has all of its Sides Equal, then it is an Equilateral Triangle

We know that In an Equilateral Triangle all Angles are Equal to 60°

⇒ (2x - 4) = 60°

⇒ 2x = 60° + 4°

⇒ 2x = 64°

⇒ x = 32°

Answer:

P(X=7)

And using the probability mass function we got:

P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271  

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:  

X \sim Binom(n=15, p=0.23)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

And we want to find the following probability:

P(X=7)

And using the probability mass function we got:

P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271

For the function f(x)=-3x+2, find f(2)=
dsp73

Answer: f(2) = -4

Step-by-step explanation: Here we're given the function f(x) = -3x + 2 and we are asked to find f(2).

In other words, if we put an <em>x</em> into our function, we get a -3x + 2 out so what happens when we put a 2 into the function?

Well if we put a 2 into the function,

that's f(2) and we get -3(2) + 2 out.

Now all we have to do is simplify on the right side.

-3(2) is -6 so we have -6 + 2 which is -4.

So f(2) is -4.
